Variable Flow Rate Dosing Pump


Blackstone’s positive displacement solenoid driven pumps use a minimum number of moving parts, therefore reducing the chance of mechanical failure. Part wear and oiling associated with motor driven pumps (ball-bearings, gear drives and cams) are not present in these pumps. Blackstone pumps are more accurate than standard pumps with the positive displacement design ensuring each stroke is identical to the strokes before and after it, thus keeping the flow rate consistent. A wide range of Blackstone pumps with different dosing capacities is available for your specific dosing needs. Each pump is supplied with discharge and suction valves.

Hanna also produces polyethylene tubing, injection fittings, ceramic weights and replacement parts. Flow Rates:

BL 1.5 = 1.5 LPH
BL 3 = 2.9 LPH
BL 5 = 5.0 LPH
BL 7 = 7.6 LPH
BL 10 = 10.8 LPH
BL 15 = 15.2 LPH
BL 20 = 18.3 LPH
